The Data
The RVC, stationary-point-count method is modified from Bohnsack and Bannerot (1986) and is conducted on shallow (<100ft), hardbottom coral reef habitats. Field surveys use a one-stage design to sample 50 m x 50 m grid cells selected using a stratified-random sampling allocation. This data set represents sample locations in the Florida Keys. Only those strata types found within the MIR areas were considered (table 1).
Fish Species
A selection of fish species were chosen to represent different trophic levels and functional roles.
Density
Density is represented as the number of individuals per 177 m^2.
Occurrence
Survey occurrence within MIR sites and outside.
Length Frequency
Relative length frequency of species within MIR sites and outside.
French Grunt
MIR_LF(df = MIR_data, spp = "hae flav", bin_size = 5, yrs = 2022, spp_name = "French grunt")
MIR_LF(df = MIR_data, spp = "hae flav", bin_size = 5, yrs = 2024, spp_name = "French grunt")
Stoplight Parrotfish
MIR_LF(df = MIR_data, spp = "spa viri", bin_size = 5, yrs = 2022, spp_name = "Stoplight parrotfish")
MIR_LF(df = MIR_data, spp = "spa viri", bin_size = 5, yrs = 2024, spp_name = "Stoplight parrotfish")
Rainbow Parrotfish
MIR_LF(df = MIR_data, spp = "sca guac", bin_size = 5, yrs = 2022, spp_name = "Rainbow parrotfish")
MIR_LF(df = MIR_data, spp = "sca guac", bin_size = 5, yrs = 2024, spp_name = "Rainbow parrotfish")
3-Spot Damselfish
MIR_LF(df = MIR_data, spp = "ste plan", bin_size = 2, yrs = 2022, spp_name = "3-spot damselfish")
MIR_LF(df = MIR_data, spp = "ste plan", bin_size = 2, yrs = 2024, spp_name = "3-spot damselfish")
Porgy
MIR_data_copy <- MIR_data
MIR_data_copy$sample_data <- MIR_data_copy$sample_data %>%
mutate(SPECIES_CD = if_else(SPECIES_CD == "CAL CALA", "CAL NODO", SPECIES_CD))
#Merged CAL CALA and CAL NODO to graph both porgy species together
MIR_LF(df = MIR_data_copy, spp = "CAL NODO", bin_size = 2, yrs = 2022, spp_name = "Porgy")
MIR_LF(df = MIR_data_copy, spp = "CAL NODO", bin_size = 2, yrs = 2024, spp_name = "Porgy")
